Prenatal Programming Of Human Neurological Function, Curt A. Sandman, Elyssia Poggi Davis, Claudia Buss, Laura M. Glynn

Psychology Faculty Articles and Research

The human placenta expresses the genes for proopiomelanocortin and the major stress hormone, corticotropin-releasing hormone (CRH), profoundly altering the "fight or flight" stress system in mother and fetus. As pregnancy progresses, the levels of these stress hormones, including maternal cortisol, increase dramatically. These endocrine changes are important for fetal maturation, but if the levels are altered (e.g., in response to stress), they influence (program) the fetal nervous system with long-term consequences. The evidence indicates that fetal exposure to elevated levels of stress hormones (i) delays fetal nervous system maturation, (ii) restricts the neuromuscular development and alters the stress response of …

Where Have All The Plant Foods Gone? The Search For Refined Dietary Reconstruction From Chinchorro Mummies, Karl J. Reinhard, Sara Le-Roy-Toren, Bernardo Arriaza

Karl Reinhard Publications

The Chinchorro cemeteries of northern Chile are the first graveyards of the Andes (Arriaza 1995, Schiappacasse & Niemeyer 1984). The excavation and analysis of Chinchorro mummies reveals the 'true character of the people'. The burials themselves are optimal for preservation of corpses, burial furniture, and aspects of ceremonies associated with the dead. The analysis of corporeal remains gradually clarifies the details of daily activities and status. Therefore, we feel that a holistic approach to mummy studies provides enormously fruitful paths to understanding the character of the ancient Chinchorro society.

Paleoepidemiology Of Intestinal Parasites And Lice In Pre-Columbian South America, Adauto Araujo, Karl Reinhard, Daniela Leles, Luciana Sianto, Alena M. Iñiguez, Martin Fugassa, Bernardo Arriaza, Nancy Orellana, Luis Fernando Ferreira

Karl Reinhard Publications

Some human parasites originated in prehominid ancestors in Africa. Nematode species, such as Enterobius vermicularis (pinworm), hookworms and Trichuris trichiura are shared by humans and other close phylogenetic primates (Pan and Gorilla), showing that they infected a common ancestor to this group. When humans migrated from Africa to other continents they carried these parasites wherever climate conditions allowed parasite transmission from host to host. Other parasites, however, were acquired throughout human biological and social evolutive history when new territories were occupied. Paleoparasitology data is a valuable source to recover emergence and disappearance of parasite infections through analysis of …

The Effects Of An Integrated Health And Physical Education Program On Student Achievement, Myralynn B. Catchings

Walden Dissertations and Doctoral Studies

In recent years, several schools have addressed the No Child Left Behind (NCLB) Act of 2001 by focusing on promoting skill acquisition in reading and math, often overlooking physical education (PE) as a significant part of a child's education. The purpose of this causal-comparative study was to evaluate the effectiveness of an integrated health and physical education (HPE) program on student achievement. This study was grounded in action-based learning theories. The research question examined differences in posttest scores, adjusted for pretest differences, from 204 freshman students enrolled in a Biology-1 class at an urban high school.

Perceptions Of Recent Male Nursing Graduates Regarding Gender Bias And Gender-Based Educational Barriers, Nancy Spahr

Walden Dissertations and Doctoral Studies

Despite decades of important contributions by male nurses, nursing is still viewed as a feminine profession. Moreover, male nursing students continue to experience gender bias and gender-based educational barriers within schools of nursing. This has led to failure and drop-out rates much higher than those experienced by their female counterparts. The purposes of this quantitative survey study were to (a) explore the relationship between perceived gender bias, gender-based educational barriers within nursing education, and resiliency in recent male nursing graduates; and (b) to identify those gender-based barriers that were considered to be most prevalent and most important. A view of …

Socioeconomic Factors Affecting Infant Sleep-Related Deaths, Catherine M. Hogan

Walden Dissertations and Doctoral Studies

Racial disparity is present in deaths attributed to sudden infant death syndrome (SIDS) and unintentional suffocation. The Back to Sleep Campaign that began in 1994 caused an overall decrease in SIDS rates, but the racial disparity has continued to increase. Researchers have analyzed and described various socio-demographic characteristics of SIDS and infant deaths by unintentional suffocation in urban areas yet have not simultaneously controlled for multiple risk factors that may contribute to racial disparity such as race, poverty, maternal education, and number of children born to each mother (parity). The purpose of this study was to determine if there is …

Drills And Exercises As Interventions To Improve Public Health Emergency Response, Donna Beth Knutson

Walden Dissertations and Doctoral Studies

The 2001 destruction of the World Trade Center and the subsequent anthrax attacks highlighted the inability of an antiquated public health system in the United States to respond effectively to emergencies. Little documentation exists to define how public health agencies can improve performance. The overarching research question was the extent to which drills and exercises improve performance in public health emergencies. Adult learning theory and deliberate practice theory were explored in this context. The research data were from 50 state public health departments, which were required to report performance information to the U.S. Centers for Disease Control and Prevention. The …

A Test Of An Evolutionary Theory Of Adiposity Gain Induced By Long Sleep In Descendants Of European Hunter-Gatherers, Oleksiy Chadyuk

Walden Dissertations and Doctoral Studies

Researchers have identified inadequate sleep duration as one of the factors contributing to global obesity. The purpose of this study was to test a hypothesis deduced from a new sleep-duration-based evolutionary theory claiming that sleep extension in response to lengthening night duration in early fall evolved into a behavioral marker of an approaching winter; this adaptive trait was theorized to produce adiposity gain in White men in response to sleep extension. The hypothesis was that White Americans would show a greater increase in the age-adjusted fat mass index per unit of sleep duration compared to that of Black Americans. Data …

Impact Of Nutrition Education On Student Learning, Lydia Singura

Walden Dissertations and Doctoral Studies

A goal of schools is to provide students with practical nutritional information that will foster healthy lifelong behaviors. Unfortunately, students at one school were found to have difficulty grasping basic nutritional information and practical health-related skills. There remains an important gap in current literature regarding strategies to improve students' understanding of nutrition education material. The purpose of this study was to investigate the benefits of a 4-week nutrition intervention unit in the Foods I classes consisting of 82 male and female students in Grades 9-12. Constructivist teaching methods were implemented to provide students with both information and valuable skills, which …

Factors Influencing U.S. Army Personnel Meeting Body Mass Index Standards, Salma Theus

Walden Dissertations and Doctoral Studies

U.S. Army Regulations require soldiers to be fit, as excessive weight negatively impacts their readiness, health, and morale. A quantitative study examined if personal, behavioral, and/or environmental factors predict a soldier's self-efficacy and body mass index. Data were obtained from 117 soldiers on 6 scales: the Armed Services Vocational Aptitude Battery, the Army Physical Fitness Test, the General Self-Efficacy Scale, the Stress Management Questionnaire, the Lifestyle Assessment Inventory, and the Multifactor Leadership Questionnaire. Multiple regression analysis was used to determine if personal (intellectual capabilities and physical fitness), behavioral (lifestyle and stress management), and/or environmental (supervisor leadership) factors predict self-efficacy and …

Discrete Trial Instruction: Comparing The Abbreviated Performance Feedback And Lecture Test Models, Tammy J. Dobbs

Walden Dissertations and Doctoral Studies

Growing media attention and a high diagnosis rate of autism places significant demand on the service industry to provide qualified staff to work with individuals who have autism. Discrete trial instruction (DTI) is one of the most sought-after treatment approaches for those individuals. However, there is a gap in research regarding the efficacy of training methods for those who train direct staff to implement DTI. This quantitative study used an applied behavior analysis basis, deriving from foundations of behavior theory, to compare the abbreviated feedback form (AFF) to the lecture test model (LTM) to understand which will improve direct staff's …

Prostate Cancer Incidence Rates In Africa, Lisa W. Chu, Jamie Ritchey, Susan S. Devesa, Sabah M. Quraishi, Hongmei Zhang, Ann W. Hsing

Faculty Publications

African American men have among the highest prostate cancer incidence rates in the world yet rates among their African counterparts are unclear. In this paper, we compare reported rates among black men of Sub-Saharan African descent using data from the International Agency for Research on Cancer (IARC) and the National Cancer Institute Surveillance, Epidemiology, and End Results Program from 1973-2007. Although population-based data in Africa are quite limited, the available data from IARC showed that rates among blacks were highest in the East (10.7-38.1 per 100,000 man-years, age-adjusted world standard) and lowest in the West (4.7-19.8). These rates were considerably …

Groundwater Uranium And Cancer Incidence In South Carolina, Sara E. Wagner, James B. Burch, Matteo Bottai, Robin C. Puett, Dwayne E. Porter, Susan Bolick-Aldrich, Tom Temples, Rebecca C. Wilkerson, John E. Vena, James R. Hébert

Faculty Publications

Objective

This ecologic study tested the hypothesis that census tracts with elevated groundwater uranium and more frequent groundwater use have increased cancer incidence.

Methods

Data sources included: incident total, leukemia, prostate, breast, colorectal, lung, kidney, and bladder cancers (1996–2005, SC Central Cancer Registry); demographic and groundwater use (1990 US Census); and groundwater uranium concentrations (n = 4,600, from existing federal and state databases). Kriging was used to predict average uranium concentrations within tracts. The relationship between uranium and standardized cancer incidence ratios was modeled among tracts with substantial groundwater use via linear or semiparametric regression, with and without stratification …

Alcohol Consumption And Risk Of All-Cause And Cardiovascular Disease Mortality In Men, Erin K. Howie, Xuemei Sui, Duck-Chul Lee, Steven P. Hooker, James R. Hébert, Steven N. Blair

Faculty Publications

This study examined the association between consumption of alcoholic beverages and all-cause and cardiovascular disease (CVD) mortality in a cohort of men (n = 31,367). In the Cox proportional hazards model adjusted for age, year of examination, body mass index (BMI), smoking, family history of CVD, and aerobic fitness, there were no significant differences in risk of all-cause mortality across alcohol intake groups. Risk of CVD mortality was reduced 29% in quartile 1 (HR = 0.71, 95% confidence interval (CI): 0.53, 0.95) and 25% in quartile 2 (HR = 0.75, 95% CI: 0.58, 0.98). The amount of alcohol consumed …

Association Between Depression And C-Reactive Protein, Yunsheng Ma, David E. Chiriboga, Sherry L. Pagoto, Milagros C. Rosal, Wenjun Li, Philip A. Merriam, James R. Hébert, Matthew C. Whited, Ira S. Ockene

Faculty Publications

Objective. Depression has been associated with increased cardiovascular disease risk, and a depression-related elevation of high sensitivity C-reactive protein (hs-CRP) has been proposed as a possible mechanism. The objective of this paper is to examine association between depression and high sensitivity C-reactive protein (hs-CRP). Methods. Subjects consisted of 508 healthy adults (mean age 48.5 years; 49% women, 88% white) residing in central Massachusetts. Data were collected at baseline and at quarterly intervals over a one-year period per individual. Multivariable linear mixed models were used to assess the association for the entire sample and by gender. Results. The …

Self-Rated Health Status And Cardiorespiratory Fitness As Predictors Of Mortality In Men, Jennifer Gander, Duck-Chul Lee, Xuemei Sui, James R. Hébert, Steven P. Hooker, Steven N. Blair

Faculty Publications

Self-rated health (SRH) and cardiorespiratory fitness (fitness) are independent risk factors for all-cause mortality. The purpose of this report is to examine the single and joint effects of these exposures on mortality risk. The study included 18 488 men who completed a health survey, clinical examination and a maximal exercise treadmill test during 1987–2003. Cox regression analysis was used to quantify the associations of SRH and fitness with all-cause mortality. There were 262 deaths during 17 years of follow-up. There was a significant inverse trend (p_trend <0.05) for mortality across SRH categories after adjustment for age, examination year, body mass index, physical activity, smoking, alcohol consumption, abnormal ECG, hypertension, hypercholesterolaemia, cardiovascular disease, diabetes and cancer. Adjustment for fitness attenuated the association (p value =0.09). The authors also observed an inverse association between fitness and mortality after controlling for the same covariates and SRH (p_trend = 0.006). The combined analysis of SRH and fitness showed that fit …

Spicing Up School Lunch: A Look At One School District's Attempts To Remedy America's Convoluted School Lunch Policies, Case Study Analysis Of Claremont Unified School District, Allison Mcelwee

CMC Senior Theses

The United States possesses a well intentioned but misguided lunch program, leaving children overfed but malnourished. Currently, a revolution is under way to transform programs around the country by incorporating locally grown and fresh ingredients, as well as integrating hands-on educational experiences with gardening and nutrition. The Claremont Unified School District (CUSD) makes up a group of schools that once heavily relied on unhealthy processed foods for providing lunch. Through a series of modifications in the past three years, CUSD’s program has been remodeled to feature more local produce and fresh ingredients, independent of USDA commodities or large scale agriculture. …

Preventing Mother-To-Child Transmission Of Human Immunodeficiency Virus-1 (Hiv-1): Effects Of Intrapartum And Neonatal Single-Dose Nevirapine Prophylaxis And Subsequent Hiv-1 Drug Resistance At Antiretroviral Treatment Initiation, Amanda L. Harmon

CMC Senior Theses

The prevention of mother-to-child transmission is one of the most powerful tools in human immunodeficiency virus type 1 (HIV-1) prevention and has huge potential to improve both maternal and child health. In the absence of any preventative measures, infants born to and breastfed by their HIV-positive mothers have roughly a one-in-three chance of acquiring the infection themselves. HIV can be passed on from mother-to-child during pregnancy, during labor and delivery, and even after during breastfeeding.

Intrapartum and neonatal single-dose nevirapine (sd-NVP) is the foundation of preventing mother-to-child transmission in lower resource settings where it has been used alone or as …

The Effect Of Female Education On Fertility And Infant Health: Evidence From School Entry Policies Using Exact Date Of Birth, Justin Mccrary, Heather Royer

Faculty Scholarship

This paper uses age-at-school-entry policies to identify the effect of female education on fertility and infant health. We focus on sharp contrasts in schooling, fertility, and infant health between women born just before and after the school entry date. School entry policies affect female education and the quality of a woman’s mate and have generally small, but possibly heterogeneous, effects on fertility and infant health. We argue that school entry policies manipulate primarily the education of young women at risk of dropping out of school.

Pick It Up, Put It Down: A Grounded Theory Study Of How Low Income African American Patients In The Deep South Start Smoking And Quit Smoking, Jessica Hillman Williams

All ETDs from UAB

The purpose of this qualitative was to use data extracted from the narrative stories of African American patients to generate a grounded theory to explain the process and act of initiating and of quitting smoking among low income African American patients in the Deep South. This is important since African Americans are more likely to suffer from smoking-related illnesses, which are the leading cause of death among African Americans. Data were analyzed from interviews conducted in 2005 as part of the Stories Project and supplementary interviews conducted in 2011. Convenience sampling strategies guided participant recruitment for primary interviews and theoretical …

Les nouvelles formes d’organisation du travail (innovations technologiques, nouvelles politiques de gestion des ressources humaines, formes innovantes d’organisation, etc.) pourraient avoir des conséquences négatives pour les individus (fatigue, stress chronique, troubles musculo-squelettiques…) et pour les établissements (absentéisme, roulement de personnel…). La documentation scientifique désigne la charge de travail comme dénominateur commun en l’occurrence, sauf que les évidences sur la conceptualisation de ce phénomène sont limitées et ne tiennent pas compte de sa complexité. Pour le définir et le caractériser, les chercheurs ont voulu déterminer les dimensions ainsi que la dynamique et …

Pcb-Contaminated Food In The Canadian Arctic: Interactions Between Environmental Policy, Cultural Values, And The Healthcare System, Katharine K. Brieger

Pomona Senior Theses

Current Canadian policies do not adequately prevent water contamination or mitigate the effects of existing polychlorinated biphenyl pollution. There is conflict between the Canadian government and the Inuit people over how to approach the pollution problem, arising from a clash of cultural values and traditions. Legislation related to healthcare is an inherently sensitive issue and some measures that seem acceptable to westernized societies are not appropriate for the Inuit. The purpose of this thesis is to answer (a) why polychlorinated biphenyls (PCBs) are in the Arctic, (b) what the effects of PCBs are on the Arctic people, and (c) how …

Prenatal Maternal Stress Programs Infant Stress Regulation, Elyssia Poggi Davis, Laura M. Glynn, Feizal Waffarn, Curt A. Sandman

Psychology Faculty Articles and Research

Objective: Prenatal exposure to inappropriate levels of glucocorticoids (GCs) and maternal stress are putative mechanisms for the fetal programming of later health outcomes. The current investigation examined the influence of prenatal maternal cortisol and maternal psychosocial stress on infant physiological and behavioral responses to stress.

Methods: The study sample comprised 116 women and their full term infants. Maternal plasma cortisol and report of stress, anxiety and depression were assessed at 15, 19, 25, 31 and 36 + weeks' gestational age. Infant cortisol and behavioral responses to the painful stress of a heel-stick blood draw were evaluated at 24 hours after …

Maternal Defense: Breastfeeding Heightens Aggression By Reducing Stress, Jennifer Hahn-Holbrook, Julianne Holt-Lunstad, Colin Holbrook, Sarah M. Coyne, E. Thomas Lawson

Psychology Faculty Articles and Research

Mothers in numerous species exhibit heightened aggression in defense of their young. This shift typically coincides with the duration of lactation in nonhuman mammals, which suggests that human mothers may display similarly accentuated aggressiveness while breast feeding. Here we report the first behavioral evidence for heightened aggression in lactating humans. Breast-feeding mothers inflicted louder and longer punitive sound bursts on unduly aggressive confederates than did formula-feeding mothers or women who had never been pregnant. Maternal aggression in other mammals is thought to be facilitated by the buffering effect of lactation on stress responses. Consistent with the animal literature, our results …

Experiences Of Older African American Women With Breast Cancer Screening And Abnormal Mammogram Results, Marshalee George

Walden Dissertations and Doctoral Studies

Even with access to well-known breast cancer treatment centers, older African American women continue to have higher breast cancer mortality compared to their European American counterparts. Researchers have theorized relationships among diagnostic delay, socioeconomic status (SES) factors, beliefs, culture, and breast cancer mortality in African American women ages 40 to 64, but these same relationships among African American women ages 65 to 80 have not been investigated. The purpose of this qualitative study was to describe older African American women's experiences with abnormal mammograms. The quality-caring model and critical race theory were used through narration to show the association of …
